HINGE.

. SPECIFICATION forming part of Letters Patent No. 700,612, dated May 20, 1902.

7 Application filed January? 1902. Serial No. 88,810. (No model.)

To all whom it may concern:

Be it known that I, AMAZON W. BRIGHT- WELL, a citizen of the United States, TGSid.

simple and novel construction described in this specification and claimed, and illustrated in the accompanying drawings, forming a part thereof, in which' Figure 1 is a rear elevation of my hinge when open. Fig. 2 is afront elevation of the same. Fig. 3 is a perspective view of the hinge with parts separated.

Like numerals of reference designate like parts in the different views of the drawings.

My hinge is constructed of two leaves, (des-f ignated by the numerals 1 and 2,respectively,)

which leaves are pivoted on a .boltor pintle 8. To provide means for connecting the hinges to the frames, three tongues are formed on each of the leaves. The contertongue 4 of each of these sets of three tongues extends in the plane of the leaf, while the two outside tongues (numbered 5) extend at right angles to the plane of the leaf., This construction braces the hinge in two directions. The leaf 1 has two knuckles 6, which are cut away on the outer sides of their inner ends to form shoulders 7. The leaf 2 has but a single knuckle 8, which is cutaway on the outer sides of both ends at 9, forming shoulders 10. The shoulders 7 and 10 are square to preventriding over and they are arranged to interlock on the upper side when the hinge is open to prevent the blind from slamming shut. As a further prevention against slamming a tongue 11 is formedintegral with the leaf 1,'is"c'urved around, and when the hinge is open passes through an aperture 12 in the leaf 2. Square notches 13 are formed in the tongue 11, which are located to engage the lower edges of the aperture 12 when the hinge is open. A lug 14. is formed on the leaf 2, which is positioned to engage an aperture 15 in the leaf 1 when the hinge is shut, which serves to strengthen the hinge and prevent the door from sagging.

When' my hinge is closed, the lug 14. will engage the aperture 15 and the higher sides of the knuckles will bear on one another. On closing the hinge it will turn on the pin 3, all the time bearing on the higher sides of the knuckles, and the tongue 11 will pass into the aperture 12. As soon as the hinge becomes straight it will drop and the upper shoulders 7 and'lO thereon will interlock and the lower notch13 will fit over'the lower edge of the aperture1 2,locking the hinge against accidental closingi'iTo/close the hinge, the

"doorto which itisapplied must be raised vertically until the notchcf'l2 is disengaged, when the door may be swung shut.

lvly hinge is perfectly symmetrical and may be turned eitherend upand is constructed from two integral blanks.

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

. Having described my invention, what I claiinas new, and Wish to secure by Letters Patent, is-' 1." In a hinge thec'ombination of two pivoted leaves having knuckles provided with shoulders locatedtointerlock when the hinge is open, a curvednotched tongue carried by one of said leaves which is constructed to engage an aperture in the other of said leaves when said shoulders interlock, substantially as described.

2. In a hinge the combination of two pivoted leaves, one of said leaves having a curved tongue provided with a square notch, the other of said leaves having an aperture there in located to be engaged by said tongue when the hinge is closed, said leaves having shoulders thereon which are constructedto interlock and permit the said square notch in said tongue to drop and engage the lower side of said aperture, substantially as described.

In testimony, whereof 'I have hereunto set my hand in presence'of two subscribing'wit- DGSSQS.
